July 28

he early morning skies are partly sunny with temperatures in the mid 50’s as Caroline, Riley and I hike on one of several paved nature trails in the city of Sherwood, Oregon, 17 miles south of Portland. On both sides of the path, I look up to see lots of tree branches covered with Usnea lichens. Also known as Old Man’s Beard, Usnea plays an important role in the ecosystem, providing food and nesting material for wildlife and contributing to nutrient cycling. It's also a bioindicator, meaning its presence or absence can indicate air quality. On a large, decaying tree trunk, I notice some lichens and mosses mixed with some wood oysterling mushrooms. In Oregon, the term "wood oysterling" may refer to several different fungi, including some true Oyster mushrooms and other lookalikes. Pausing by a small pond, I watch a group of Mallard hens and juveniles swimming around. Near the far shore, I spot, but am unable to photograph, the head of a swimming muskrat-like rodent, called a Nutria (stock photo). This semi-aquatic mammal, native to South America, was originally brought to the US in 1889 for its fur. When the fur market collapsed in the 1940s, thousands of them escaped or were released into the wild by ranchers who could no longer afford to feed and house them. Nutria are voracious herbivores, known for clearing areas of their vegetation. Coupled with their proficiency in traveling both on land and in water, they pose a significant threat to the environment, particularly wetlands. Up ahead, I observe the pink blossoms of a native, deciduous shrub called Douglas Spirea, also known by other common names like hardhack and steeplebush. Named after David Douglas, this 19^th century, Scottish botanist also has his name attached to the Douglas Fir. Nearby, I notice pink blossoms of Japanese Spirea, a small, invasive shrub native to Japan, Korea and China. Among the floating pond weeds covering the pond surface, I spot the head of a Bullfrog with its large, bulging eyes that sit at the top of its skull. The location of its eyes gives it a wide frame of vision, which is important because it cannot move its head from side to side. These amphibians are carnivore that eat crayfish, water beetles, snails, dragonfly nymphs (larvae), small fish, and occasionally small birds. Animals such as snapping turtles, foxes, herons, and raccoons eat them. Continuing down the path, lined with snow-like Cottonwood seeds, my ears perk up to the song of a Spotted Towhee (stock photo) and a Steller’s Jay (stock photo) Turning around and approaching the car, I see the familiar blossoms of Queen Anne’s Lace as well as 10-inch wide leaves of Bigleaf Maple.

Who will raise their voices

With arguments and pleas

Who will speak for the creatures

Who will defend the trees

Wildlife are in peril

Their habitats shrink

Some are threatened

Others on the brink

Respect living things

Conserve and care

Revere them all

This planet we share

The early morning sky is sunny with temperatures in the upper 60’s as Caroline and Riley join me for a hike in the 2.2 million-acre Yellowstone National Park. Soon we come upon a small pond where several dragonflies flutter above the surface. Exploring the bank, I spot some of these, including a Western Pond Hawk, a White-faced Meadow Hawk, and a Paddle-tailed Darner. Also, I see a lovely Spread-wing Damselfly. Circling the pond, I spot a patch of Golden Paintbrush blossoms as well as a lovely blue blossom of Fringed Gentian. Driving a short distance, we find a vacant campground with a sign on one of the picnic tables that reminds us we are in Yellowstone Park, not Conservation Park in Alma. Exploring this area, I come upon a patch of Harebells. The Haida Indians of the Pacific Northwest called them "blue rain flowers" and it was thought that picking them would cause it to rain. Nearby, I see white blossoms of Richardson's Geranium, named after Sir John Richardson, a 19^th century Scottish naturalist, explorer, and surgeon. Next, I come upon a Twinberry Honeysuckle shrub. While its berries are a valuable food source for wildlife, they are not recommended for human consumption. Scattered on the ground are frisbee-size mounds of dried Buffalo dung. Bison feces is an important natural fertilizer for microbes, plants and other animals. This natural biologic function is a fundamental means of nutrient flow on the grasslands and woodlands in the park. Up ahead, I pause to observe the reddish stalks of Woodland Pine-drops. Lacking chlorophyll, this saprophyte derives its food from dead and decaying plant material, especially the deep humus found under Lodge-Pole and Ponderosa pines. Hiking near our cabin rental, I pause, along with other tourists, to watch the Old Faithful geyser erupt, an event happening nearly every 90 minutes. Yellowstone Park boasts a high concentration of geysers due to a shallow magma chamber that provides the intense heat needed to superheat groundwater, while rainwater and snowmelt seep into the ground, forming underground reservoirs. Fractures and faults in the rock act as a plumbing system, allowing the heated water to rise rapidly and erupt as geysers. After the eruption, I notice some of this heated water carrying high amounts of calcium carbonate, cool and form a chalky white landscape while some of the water spills into the passing river. Down river, I spot a few Common Mare’s Tails poking out of the flowing water. This perennial herb can be a troublesome weed, obstructing the flow of water in rivers and streams.

 

One early morning

One human finds

Steamy geysers

Lodge pole pines

One life grateful

We saved this place

For nature’s wonders

To have their space

Bison and bears

Make their mark

One of a kind

Yellowstone Park

The early morning sky is mostly sunny with temperatures in the mid 60’s as I, once again, enter a conservation easement of the Chippewa Watershed Conservancy for my annual inspection of this 38 -acre Gratiot County property.  Right away, I spot the head of a Whitetail buck sticking out of tall grasses, displaying his velvet-covered antlers. Most bucks will complete their antler growth in the middle of August. In late August through mid-September, the velvet dries up and they rub it off.  Just ahead, I notice a Milkweed beetle resting on a Milkweed leaf. Like Monarch butterflies, these beetles accumulate cardenolides from Milkweed, making them unpalatable to predators, a defense they advertise with their striking orange and black markings.  Continuing along, I watch a Bumblebee and a small Sweat Bee feed on small yellow blossoms of Common Mullein. Sweat bees are important pollinators for many wildflowers. As their common name suggests, these bees are attracted to the salt found in human perspiration. Off in a distant field, I look at and listen to a breeding pair of Sandhill Cranes. These lovely birds mate for life - which can mean two decades or more - and stay with their mates year-round. Looping back, I find some Hairy Vetch plants with their lovely purple blossoms. This plant is a highly effective nitrogen fixer, extracting nitrogen from the atmosphere and making it available to plants in the soil, reducing the need for synthetic fertilizers. Pausing at one of several ponds, I first listen to a few Green Frogs and then spot a needle-like Bluet Damselfly perched above the water on blade of grass. Nearby, I see a Cabbage-white Butterfly feeding on Catnip blossoms. This butterfly is a common species whose caterpillars, called cabbageworms (stock photo) are considered a significant pest of crops like cabbage, kale, and broccoli. On my way back to the car, I pass a large patch of Chamomile blossoms. This plant has been used for centuries for its medicinal effects. It is commonly consumed as an herbal tea and is also used in cosmetics and aromatherapy. Nearing the car, I spot a Japanese Beetle resting on a False Sunflower blossom. This native Japanese insect, first discovered in the US in 1916, is a significant pest of landscape trees and shrubs as well as vegetable and fruit crops.  

Beauty of summer

settles over the water

where a cardinal flower

flaunts its scarlet pedals, 

a wood duck drake parades

its coat of many colors.

In the murky depths

beauty awaits its cue.

An unsightly creature

heeds its inner call to

ascend and transform. 

Behold! Dragonfly, 

adorned with translucent

wings and body of 

iridescent green.

The early morning temperatures are in the upper 60’s with a refreshing breeze at my back as I hike on a mowed trail toward the rising sun while being entertained by a Song Sparrow. Today, as a volunteer for the Chippewa Watershed Conservancy, I’m evaluating one of their 38 conservation easements, a 24-acre privately-owned parcel east of Alma. This property was purchased years ago with government funds with the understanding that the landowner would maintain it as wildlife habitat. My job is to determine if there’s compliance and report the results to the Conservancy. Up ahead, I watch a butterfly flutter by and land on the grassy ground. Upon a closer look, I see it’s a 1-inch, Common Wood-Nymph displaying an eyespot on one of its wings. These eyespots are thought to play a role in predator defense, potentially confusing or deterring birds and other predators. Nearby, I spot a resting 1-inch, White Slant-line Moth. Their caterpillars are twig mimics. Their brown, narrow bodies hold on to a branch at one end and stretch away from the branch to hide among the twigs and leaves (stock photo). On another blade of grass, I notice a ½-inch, strange-looking collection of small twigs, containing a Bagworm. In the life cycle of certain moths, the caterpillar spins a cocoon-like bag on which pieces of leaves and other plant parts are attached. The bag acts as a portable shelter and camouflage, shielding the caterpillar from predators and harsh weather conditions. Further along, I come upon a male 12-spotted Skimmer Dragonfly. Both male and female have 12 dark brown wing spots while the male has 8 additional white wing spots. Looking around, I spot a Widow Skimmer Dragonfly. This dragonfly got the “widow” name because, unlike most other dragonfly species where the male stays near the female after she lays her eggs, the male in this pair leaves her after the eggs have been laid.  As with other dragonflies, eggs are laid in ponds where they hatch. The nymphs (stock photo) live in the water, molting and growing until they are ready to emerge from the water.  Coming upon one-of-many Cottonwood trees, I spot a leaf displaying an abnormal, swollen growth called a Petiole Gall. In the spring, aphids hatch from eggs laid on the Cottonwood tree and begin feeding on the petioles of newly emerging leaves. This feeding stimulates the plant to produce a growth around the aphids. Theses galls provide a safe environment for the aphids to grow and reproduce. While the galls may be noticeable, they generally do not harm to the tree. 

Nature in rhythm

July days ahead

Summer sky blue

Raspberries red

Creatures are born

Consume and grow

Vultures fly high

Frogs lie low

Pond water wanes

Below the brim

Neath the surface

Mudminnows swim
